Mechanism too loud
My cats have had a cat flap for 13 years and always used it without any problems, but it never had an outside lock! Now I had to activate it because of strange cats coming in, and my cats won’t go through anymore because the mechanism scares them! As soon as they put their heads in the tunnel, it makes a really loud click and they back away and run off! Now they don’t want to use it even without the lock! I’ve tried every suggestion out there for weeks! Nothing works! HELP!
